Seismic
Earthquake: "An earthquake is the result
of a sudden release of energy in the
Earth's
crust
that creates
seismic waves.
Earthquakes are recorded with a
seismometer,
also known as a seismograph. The
moment magnitude
of an earthquake is conventionally reported, or
the related and mostly obsolete
Richter
magnitude, with magnitude 3 or lower earthquakes
being mostly
imperceptible
and magnitude 7 causing serious damage over
large areas. Intensity of shaking is measured on
the modified
Mercalli scale.

Tsunami: "A tsunami
(pronounced
/(t)suːˈnɑːmi/)
is a series of
waves
created when a body of water, such as an
ocean,
is rapidly displaced.
Earthquakes,
mass movements
above or below water, some
volcanic eruptions
and other
underwater explosions,
landslides,
underwater
earthquakes,
large
asteroid impacts
and detonation of
nuclear weapons
at sea all have the potential to generate a
tsunami. The effects of a tsunami can be
devastating due to the immense volumes of water
and energy involved. Since
meteorites
are small, they will not generate a tsunami."

Volcanoes: "A
volcano is an opening, or rupture, in a planet's
surface or
crust,
which allows hot, molten rock, ash, and gases to
escape from below the surface. Volcanic activity
involving the
extrusion
of rock tends to form mountains or features like
mountains over a period of time.
Volcanoes are generally found where
tectonic plates
are
diverging
or
converging.
A
mid-oceanic ridge,
for example the
Mid-Atlantic Ridge,
has examples of volcanoes caused by "divergent
tectonic plates"
pulling apart; the
Pacific Ring of Fire
has examples of volcanoes caused by "convergent
tectonic plates"
coming together." Source:
